Exterior Defrost System for Automobile

ABSTRACT

An exterior defrosting system for a motor vehicle comprising: a heat source; a systems of ducts arranged on the under side of the vehicle; and a plurality of vents along the duct system, where the vents provide a stream of hot air on the underside of the vehicle. In one exemplary embodiment, at least one vent may be positioned near each wheel of the vehicle. A heat source such as a vent box may force air through the duct system, where the plurality of vents is placed a frame of the motor vehicle.

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a defrosting system that providesheated air streams to critical areas of automobile's exterior.

2. Description of Related Art

As many individuals are aware operation of an automobile during orwithin a cold environment comes with several problems and drawbacks.Many times in the cold environments in particular winter months snow andice accumulates on driveways, parking lots, roadways and therefore makesit hazardous for the operation of a motor vehicle. The ice and snowmakes it difficult for the tires of the vehicle to obtain sufficienttraction for the movement of the vehicle over the roadway. If aparticular vehicle were to somehow become stuck within the snow or icethe only alternative many users have is to physically shovel or dig thevehicle out of the situation or alternatively call for tow truckassistance for the movement of the vehicle. Consequently, it would beadvantageous to have a device equipped on the vehicle that may providesufficient heat to melt snow and ice near and around the vehicle'swheels. The distribution of heat in these key areas could assist thedriver in the maneuvering the vehicle through the ice and snow and avoidbeing stuck in such conditions.

SUMMARY OF THE INVENTION

The present invention relates to an exterior defrosting system for amotor vehicle comprising: a heat source; a systems of ducts arranged onthe under side of the vehicle; and a plurality of vents along the ductsystem, where the vents provide a stream of hot air on the underside ofthe vehicle. In one exemplary embodiment, at least one vent may bepositioned near each wheel of the vehicle. A heat source such as a ventbox may force air through the duct system, where the plurality of ventsis placed a frame of the motor vehicle.

BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 depicts a schematic overview of a heating system for the exteriorof an automobile.

FIG. 2 depicts a bottom view of the heating system for the exteriorheating system according to the present invention.

FIG. 3 depicts a side view of the duct system related to the heatingsystem according to the present invention.

DETAILED DESCRIPTION

The present invention provides a venting system that distributes heat atcritical areas along the exterior underside of a motor vehicle accident.The venting system according to present invention uses a blower that ispowered via the vehicle's battery. The blower distributes heat createdby the vehicle's heating system and places a stream of heat near thewheels and underside of the vehicle in order to melt any surroundingsnow or ice.

FIG. 1 depicts a schematic of the heating system as it relates to thewheel structure of an automobile. A motor vehicle accident with fourwheels 35 a, 35 b, 35 c, 35 d or placed upon the axels of the vehicledepicted in FIG. 1. Fenders 42 a, 42 b, 42 c, 42 d surround each wheelas shown. A Drive Shaft 32 extends from an Engine 30 to a differentialAxel 34. Vents are provided at the sides of the vehicle as shownconnected to a Frame 21 a on one side and Frame 21 b on the opposingside. Vents 15 a, 15 b are shown along the Frame 21 a and on theopposite side Vents 15 c and 15 d are shown on the Frame 21 b. Airsupplied by the heating system according to present invention is emittedfrom the vents and transferred to the underside of the vehicle.Crossbars 22 a, 22 b extend across and connect the Frame 21 a, 21 b.

FIG. 2 depicts a system of the ducts that are incorporated in theheating system according to the present invention along the undersidenear the wheels 35 a, 35 b, 35 c and 35 d. Wheel Ducts 17 a, 17 b, 17 cand 17 d are placed at each respective wheel as shown in FIG. 2. SideDucts 18 a and 18 b are on each respective side of the outer undersideof the Vehicle 100. These ducts distribute the warm air to and near thewheel base area of the Vehicle 100. FIG. 3 depicts a side view of theheating system and shows a vent Box 12 which is connected to the ductsystem of FIG. 2, where one side is shown in FIG. 3. The vent Box 12emits a warm stream of air through the ducts and allows for the emissionof heated air both at the wheels 17 a, 17 c and along the sides Frame 15a from Vents 15 a and 15 b. This heated air is further distributedthrough the side Vent 18 a.

Use of the heating system according to present invention as describedabove helps to melt snow and ice near the wheels of the vehicle andtherefore provides an exterior defroster for the subject vehicle. Thedefrosting system according to present invention may be controlled bycontrol panels within the driver compartment of the vehicle. The heatingsystem operates whether the vehicle is in motion or stationary and itincludes blowers that push the heated air through the ducts of theheating system as shown in FIGS. 1 through 3. The heating systemprovides a direct flow of hot air at critical positions along thevehicle. The instant invention has been shown and described in what itconsiders to be the most practical and preferred embodiments. It isrecognized, however, that departures may be made there from within thescope of the invention and that obvious modifications will occur to aperson skilled in the art.
